BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic view of a polishing apparatus according to an embodiment of the present invention.

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

Referring to FIG. 1, a polishing apparatus 100 according to an embodiment of the present invention is used to polish a rod 200 such that one end thereof forms a spherical surface, so that the rod 200 has a shape of a conventional hand-held fragrance.

The material of the rod 200 is acrylic or PC, and the shape of the rod 200 may be a shape similar to a conventional hand-held fragrance such as a cylinder, a hexahedron or an octahedron.

The polishing apparatus 100 includes a polishing wheel 20, a motor 30, a fixing mechanism 40, a moving mechanism 50, and a blowing mechanism 60. The motor 30 is used to drive the polishing wheel 20 to rotate, the moving mechanism 50 is used to move the rod body 200 back and forth relative to the polishing wheel 20, and the fixing mechanism 40 is used to fix the rod body 200 so that the rod body 200 does not rotate relative to the moving mechanism 50 during the movement of the rod body 200. , blowing mechanism 60 Used to blow off the debris in the polishing wheel 20.

The polishing wheel 20 includes a body 21, a polishing portion 22 and a guiding portion 23, and the polishing portion 22 and the guiding portion 23 are recessed on the body 21, the guiding portion 23 is for guiding the movement of the rod body 200, and the polishing portion 22 is used for polishing the rod body 200. To have one end form a specific shape.

The body 21 may be a cylinder, a hexahedron or an octahedron or the like. The guide portion 23 is recessed inwardly from one end of the body 21, and the guide portion 23 has a circular cross section. The polishing portion 22 is further recessed toward the inside of the body 21 by the guide portion 23, and is a concave spherical surface. The radius of the polishing portion 22 is equal to the radius of the spherical surface on the rod 200, and the radius of the guide portion 23 is equal to the radius of the polishing portion 22.

In the present embodiment, since the end portion of the rod 200 is required to be formed into a hemispherical surface, the polishing portion 22 is a one-half concave spherical surface.

The surface roughness of the polishing portion 22 is 0.2 μm to 0.8 μm; the guide portion 23 may be a smooth surface, and the surface may have a roughness of 0.2 μm to 0.8 μm.

The material of the polishing wheel 20 may be ceramic, resin, rubber or metal.

The motor 30 has a rotating shaft 31. The polishing wheel 20 is fixed on the rotating shaft 31. When the motor 30 is in operation, the rotating shaft 31 rotates, and the rotation of the rotating shaft 31 can drive the polishing wheel 20 to rotate.

The fixing mechanism 40 is used to fix the rod 200 to prevent the rod 200 from rotating during polishing. The fixing mechanism 40 includes two semi-circular collars 41 and screws 42 having the same structure. The collar 41 has a screw hole, and the screw 42 is screwed into the screw hole to sandwich the rod 200 between the collars 41, and is locked. The collar 41 secures the rod 200.

The moving mechanism 50 is coupled to the fixing mechanism 40 for moving the rod 200 to move the rod 200 back and forth relative to the polishing wheel 20.

When the rod 200 is polished by the polishing apparatus 100, the rod 200 is passed between the collars 41 and the collar 41 is locked by screws 42 to fix the rod 200 to the fixing mechanism 40, and the motor 30 and the moving mechanism 50 are activated. Thereby, the polishing wheel 20 is rotated and the rod 200 is moved toward the polishing wheel 20, respectively. The rod 200 enters the polishing portion 22 under the guidance of the guiding portion 23, and the polishing portion 22 is in contact with the rod 200 to grind the surface of the rod 200. After polishing for a period of time (for example, 10 seconds), the moving mechanism 50 drives the rod 200 to move away from the polishing wheel 20, at which time the blowing mechanism 60 blows into the guiding portion 23 and the polishing portion 22 of the polishing wheel 20 to The debris generated during the grinding process is blown off.

During the continuous contact of the rod body 200 with the polishing portion 22, one end of the rod body 200 is continuously polished by the polishing portion 22, so that the end portion of the rod body 200 has the same curved surface as the polishing portion 22.

In addition, after the rod 200 is in contact with the polishing portion 22 for a period of time, the moving mechanism 50 drives the rod 200 to move away from the polishing wheel 20, so that the blowing mechanism 60 can blow off the debris inside the polishing wheel 20, and then again The rod 200 moves into the polishing portion 22, and if the debris is not blown off, the debris accumulates in the polishing portion 22 and the guide portion 23, and the rod 200 cannot move to the polishing portion 22, so that the polishing process cannot be performed.

The polishing wheel 20 of the present embodiment has a polishing portion 22 having the same shape as the spherical surface of the end portion of the rod body 200. The rod body 200 is continuously ground under the polishing portion 22 to form a spherical surface, so that the polishing of the rod body 200 can be completed with time and labor, and each One rod 200 has the same spherical structure.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
